' WIRE-HAT-FRAME-MAKING MACHINE.

To all whom it may concern:

Be it known that I, JOSEPH A. SCHWARTZ, a citizen of the United States,and a resident of the city of Philadelphia, county of Philadelphia,State of Pennsylvania, have invented an Improvement in \Vire-Hat-Frame-Making Machines, of which the following is a specification.

My invention has reference to wire hat frame making machines andconsists of certain improvements which are fully set forth in thefollowing specification and shown in the accompanying drawings, whichform a part thereof.

The object of my invention is to provide a suitable construction ofmachine for the making of wire hat frames by the general method employedin making wire hatframes on plaster of Paris blocks but with capacity ofmaking an infinite number of different shaped frames to suit thechanging of the styles.

My obpect is also to provide in such machine capacity for making wirehat frames with deep rims, a feature which has not been possible withplaster of Paris blocks.

My invention consists of certain features of construction which areclearly illustrated in the drawings, fully described in the specification and more specifically defined in the claims.

Figure 1 is a plan view of a machine embodying my invention; Fig. 2 is aplan view of one of the radial plates forming a part of the block; Fig.3 is a cross sectional elevation of my improved machine; Fig. 4: is aplan view of the structure of one of the radial arms and itsconnections; Fig. 5 is a cross section of one of the radial arms and anelevation of the outermost vertical bar; Fig. 6 is a sectional elevationof detail in connection with the vertical bar; Figs. 7

and 8 are perspective views of the bar clamps; Fig. 9 is a sectionalelevation of a modification of the supporting means for the radial arm;and Fig. 10 is a perspective view of an angular washer used on mymachine.

2 is a turn-table and is pivoted upon a base 3. The turn-table may havesockets 4: for receiving the inner ends of radial arms 5 of which thereis preferably six, but I do not restrict myself tothe number of thesearms. The radial arms .5 are recessed at the back as at 6 and providedwith a longitudinal slot 7. The upper and lower part of the arms arenotched to form longitudinal slots Specification of Letters Patent.

6 when the back plate 8 is secured in position.

2]. and 21 are a series of clamps which are arranged within the recessedportion 6 of the radial arms and have screw threaded portions 22 whichextend through the slot 7 of said arms, and nuts 23 are arranged uponthe screws for drawing the clamping portions into the recess. Thevertical bars 9 extend downward through the slots 6* and through clamps21 and by means of said clamps are drawn tightly against the arm so asto be held in any vertical adjustment desired. In the matter of thevertical bars 9 and 10 at the innermost ends of the radial arms 5, Iemploy a clamp 521 (Fig. 8) which has a wider slot so as tosimultaneously clamp both bars, the said bars resting against eachother, as will be clearly understood by refercnce to Fig. 3. It willalso be necessary in making some forms of hat brims to bring the bars 15and 20 close together, and in which case one of the double clamps 21would be employed instead of the single clamps, this being a mere matterof detail and dependent upon the shape of the hat frame to be made.

All of the vertical bars 9, 10 and 20 are each provided at the top withnotches to form hook portions. said hook portions be ing shown in thebars 9 and 10 at 12 in the bars 20 at 12, and said bars are alsoprovlded with lateral arms or supports 13 which may be provided at theouter ends with L shaped clamping hooks 9st which may be drawn downtoward the arms by nuts 25 (Fig. 6).

The innermost bar 10 of each of the radial arms has its upper end 14made with an overhand so that the arm 13 and the hook 12 thereof comeimmediately over the adjacent bar 9 and its hook and lateral arm, saidconstruction being clearly shown in Fig. 3. This enables the uprightpart of the crown of the hat to be made vertical.

The outermost bar 15 is made bifurcated, as shown in Fig. 5, wherebythere is a space 17 formed between the forked upper end. The upper endsof the bar are provided with notched or hook shaped portions 16 whichare screwed down into place. 18 is a sheet metal plate which is held tothe several lateral supports or arms 13 by the clamps 24; and the innerend of this plate is bent over the uppermost arm 13 of the bar 10 andmay be clamped thereon by one of the clamps 24;

supplemented, if desired, by an angular washer 26 constructed andarranged as illustrated more particularly in Figs. 4: and 10. Theoutermost end of the sheet metal plate 18 is bifurcated, as indicated inFigs. 2 and 4. The ends 19 and 19 have apertures by which they areclamped in position upon the ends of the two upper parts of thebifurcated bar 15 by means of the clamping hook shaped part 16, asclearly indicated in Figs. 4: and 5. It will be noted that the end 19 ofthe plate 18 is extended beyond the normal edge of the plate, the objectbeing to reach the top of the main portion of the bar 15, which isarranged in line with the remaining bars, and hence to one side of thelateral edge of the sheet metal plate 18. These plates 18 of the severalarms provide surfaces which correspond to the surfaces of a plaster ofParis hat frame block, and act as guides for the wires employed inmaking the hat frame, said wires being indicated at 27, 28, 29 and 30 inFig. 4.

There the outer rim of the hat frame is to have considerable depth andvertical shape, as indicated in Fig. 3, it is necessary to employ a bar20 between the bars 9 and 15, otherwise the rim of the hat frame wouldnot be of sufficient strength, and for this purpose the bar 20 has thehooked portion 12 offset with respect to the laterally protecting arm orsupport 13, so that when the plate 18 rests against the lateral arm 13,the hook portion 12 will be arranged inward with respect to the innerface of the plate, as shown in F ig, 3 so as to receive and hold thehorizontal wire which is to be incorporated in the hat frame.

In employing my improved hat frame block machine, I arrange the severalbars, 9, 10 and 15, with or without the bar 20 as the case may require,upon the radial arm with the hooks 12 arranged so as to provide theright shape of the hat with respect to the horizontal wires. The sheetmetal plate 18 is then bent and clamped to the arms 13 and to theoutermost bar 15, as previously described. Each of the radial arms 5 hasits bars adjusted in proper position, and itis pointed out that thesebars on one radial arm need not be adjusted in the same relation as thebars on another radial arm, as it is manifestly evident that the hatneed not be circular and need not be symmetrical as to height allaround. lVhatever the shape desired my be, it is insured by the properadjustment of the bars for receiving the horizontal wires. After theadjustment, the horizontal wires 28 (Fig. a) are hooked around the hooks12 of the corresponding bars of each radial arm. The cross or radialwires 27 are then twisted about the outermost wire 28 as a point betweenthe two hook shaped clamps 16, as indicated at 30 in Fig. l, and it isthen bent upon the remaining wires 28 and attached to them by the tyingwires 29 and the extreme opposite end of said wire 27 is secured to theoutermost wire 28 by being similarly twisted about it at the outermostpart of the diametrically opposite radial arm and corresponding to whatis indicated in 30 in Fig. 4. The plates 18 act as surfaces forsupporting the wires 27 and at the same time acting as guides for theoperator in introducing and operating upon the tying in wires 29 in amanner corresponding to the surfaces of the plaster of Paris hat blocks.

hen the hat frame is finished, it may be disconnected from the hookportions 12 and 12 by being sprung therefrom, or if desired, thisdisengaging operation may be facilitated by making the radial arms 5adjustable so as to swing the upper ends of the vertical bars toward thecenterof the machine to a slight extent to disengage the hooks from thehorizontal wires 28. Any suitable mechanism may be employed for thispurpose and by way of illustration, the construction shown in Fig. 9 maybe used. In this case, the radial arms 5 are hinged to the turn-table 2at 36 and have outwardly extending lugs acted upon by springs 31 tooscillate the arms 5 toward each other and toward the center of themachine. cooperating with the turn-table act to limit the inward.movement of the arms 5. A ring 34 is screwed upon the outer part of theturntable 2 and is provided with an inwardly directed flange 32 whichextends over the lugs on the radial arms 5 so that when the ring 34 isscrewed down, the arms 5 are brought into their operative position formaking the hat frame, but when the ring 34 is screwed upward, thesprings 31 are allowed to act upon the'arms to force them toward eachother and release the hat frame.

While I have shown my improved apparatus in the form which is adaptedfor good commercial practice, I do not restrict myself to the details,as these may be modified in various ways without departing from thespirit of the invention.
